Ingestion status — operator view

For: Platform UI · File: Figma · Ingestion / status (link the file; this is the packet) · As of: 2026-08-12

Overview

Operators need to see whether ingestion is healthy without opening four dashboards. In-scope: a single status page for queue lag and shed count. Out of scope: producer configuration.

User flow

1. Open Status.
2. See current lag and whether shed is active.
3. If lag is high, follow the runbook link.

Screens

• Happy — lag under 30s, shed count zero.
• Empty — no events in 15 minutes. Copy: "No events in the last 15 minutes. Producers may be idle."
• Loading — skeleton bars, no fake numbers.
• Error — dashboard query failed. Copy: "Status unavailable. Try again, then page Platform."
• Success — not a toast; the happy state is the success.

Components

Use StatusBanner, MetricCard, Button from the platform system. No custom chart — a number plus a 15-minute sparkline from Sparkline. Do not introduce a new accent; use the system danger token for shed-active.

Interaction

Focus order: title, lag metric, shed metric, runbook link. Keyboard: tab through; Enter on the runbook link. No motion beyond the existing 150ms fade on number change. Honour prefers-reduced-motion.

Responsive

One column below 720px. Two metric cards stack; do not shrink type below 16px.

Content

Lag label: "Queue lag". Units: seconds. Truncate shed counts with SI (1.2k), not "1200.00". Empty strings are the empty-state copy above — never blank cards.

Data

Lag from ingest_lag_seconds. Shed from dispatcher_shed_total (zero until RFC 014 ships — show the metric, value 0, no "coming soon"). If the operator lacks the dashboard role, hide the page behind the existing 403, do not show zeros.

Accessibility

Metric numbers have visible text, not colour-only. StatusBanner uses text + icon. Contrast already in the system; do not override.

Acceptance criteria

• Given lag 12s and shed 0, when I open Status, then I see 12 and 0 and no error.
• Given the query fails, when I open Status, then I see the error copy and no invented lag.
• Given a viewport 375px wide, when I open Status, then both metrics remain fully visible without horizontal scroll.
